Back

noncollinear points

Front

don't lie on same line

Back

Front

facts/rules about geometry that have been proven true

Back

point

Front

named by using a capital letter

Back

ray

Front

straight line made up of points, has begging but no end, starting point of this is called an endpoint, name using the endpoint first and another point on it.

Back

plane

Front

2 dimensions, extends without end in all directions, takes at least 3 noncollinear points, named with a single uppercase script letter or by 3 noncollinear points.

Back

ruler postulate

Front

the distance between 2 points is the absolute value of the difference of the coordinates of the points

Back

Front

adding angles within one large angle to find the large angle

Back

segment addition postualte

Front

if b is between a and c, then ab+bc=ac

Back

segment bisector

Front

segment, ray, line, or plane that intersects a segment at its midpoint

Back
